Secure 3 phase digital energy meter is an electronic device used to measure and record the electrical energy consumed by a three-phase electrical system. It typically includes a digital display that shows the total energy consumption in kilowatt-hours (kWh) and may also include additional features such as the ability to measure and display power factor, voltage, and current. Some digital energy meters can also be connected to a remote monitoring system, allowing energy usage data to be collected and analyzed remotely. These meters are commonly used in commercial and industrial settings to accurately measure and track energy consumption.
